I did get a new electric fuel tap about 15 years ago not long after I bought the bike (one wire had snapped where it comes out of the resin that seals it). But the 'new' tap is playing up these days, and seems to stick open sometimes. Which is a bit of a pain (I ran out of fuel one night - with massive amounts of luck it first cut out 200 yards from home, restarted and ran dry totally as I pulled on to the drive).

Looks like the year is starting off right - the YB10 is finally running. I was surprised that the bike would start after sitting around all this time but it did.

So to recap, the tank was lined to prevent expansion caused by use of ethanol in the fuel. I use highest octane gas sold in my area, which is 91. I know that for many Euro regions this is equivalent to an average octane rating but I have to work with what I got.

I used two Acerbic petcocks with outlets facing each other. A T-Connection was used to connect the fuel lines coming off each petcock to the line going to the filter and then onto the fuel pump. I bought a Pingel filter and was originally trying to figure out the best way to run the fuel lines under the tank without crushing them catastrophically. In the end, I went with a plastic fuel filter (thanks Katy). I also used a 90* quick disconnect from Beemer Boneyard to allow for easier tank removal.

The Dieci is going to the tuner in order to dial in the bike properly and get it ready for the street and eventually the Quail Motorcycle Run taking place in May. Thanks to all who have shared their knowledge and offered words of wisdom.

This project should have never taken so long. Its really a several week affair that includes waiting for the tank to be lined. This was just me not being on the point, getting sidetracked, and spending way too much time overthinking the process._________________1991 Bimota YB10

I use highest octane gas sold in my area, which is 91. I know that for many Euro regions this is equivalent to an average octane rating but I have to work with what I got.

Europe and the USA tend to use different octane rating systems. The 2 main systems are RON and MON, with as a rule of thumb the MON rating being 10 points lower than the RON rating of the same fuel. The USA uses the PON (pump octane number) which is an average of the RON and MON figures. So rule of thumb 5 points lower, and so about European 96 octane. Standard European unleaded (confusingly called premium - there used to be a lower grade available in some European countries) is 95 octane so you are slightly above that.

Having that that, from memory Japanese bikes from the early 1990s tended to be set up for fairly low octane fuel. Have a feeling the FZR might have been designed for 91 RON.

Called Jett Tuning in Camarillo, CA and they will take the bike in for a refresher. I can't wait to get back on it. My friend who's been riding with me for years noted that I was the happiest when riding the Dieci. Let the good times roll..._________________1991 Bimota YB10
